【答案解析】
   Friendship is an eternal theme in human history. A life without friendship is hard to imagine. Real friends can share all our sorrows and double all our joys. So it is a delight to make friends from all walks of life. However, some people hold that friendship can be easily affected by financial disparity. As far as I am concerned, I firmly believe true friendship has nothing to do with fame, power, or possessions and will never be spoiled by them.
   In the first place, friendship implies loyalty, cordiality, sympathy, affection and readiness to help and real friendship is largely built on sincerity and respect from both sides rather than on the two persons' family background, or mutual financial profits, and the like. True friends would often watch silently from afar when you are influential, but come to you whenever you need their help. They care not what you are, but who you are. For example, students in the same dormitory at college often take time and effort to develop friendships among them regardless of the financial gap between them. By doing so they have a better understanding of each other, learn to show respect to each other and tend to help each other a lot when necessary, without caring too much about their personal interests.
   Secondly, perfect friendship is based on goodness. Only the friendship of those who are good, and similar in their goodness, is perfect. As the saying goes, true friends must go through trials and tribulations together. Therefore, those mutual relationship based on finance are not real ones and will be vulnerable when confronted with any tests.
   Generally speaking, true friends can stand tests of any kind regardless of time and money. As long as two people have mutual tolerance and understanding, the friendship can last for a lifetime.
